Senior Software Engineer

The iOS Developer Experience team builds all necessary infrastructure and tools to ensure Block’s iOS development can continue to be fast and efficient at scale. This is a high force multiplier team aiming to enhance the developer experience for all iOS developers at Block. Our focus is on improving both the local IDE and CI experience when working within our massive and modularized monorepo codebase. We're betting heavily on the future of Bazel. We've already made a 4x improvement on compilation speed and 2x improvement in CI turnaround, but there is still a lot more room for improvement. We do our work in the open, on GitHub, and progress can be seen in the bazel-ios project on GitHub.
